Abstract: In this talk I will consider the problem of explicitly computing the graded perverse sheaf associated to the weight filtration on the sheaf of nearby cycles for some Shimura varieties with Iwahori level structure. Using an explicit formula for the semi-simple trace of Frobenius on nearby cycles (earlier joint work with B.C. Ngo) together with Gaitsgory's observation that inertia acts purely unipotently on the nearby cycles, one can give an algorithm to compute the graded pieces in the...

Speaker : Omer Egeciogiu Keywords: Analysis of algorithms; 4-term recursions; Hankel determinants; alternating sign matrices. Abstract: There is surprising connection between a certain transform on real polynomials and a number of combinatorial structures. We discuss the elements of this connection and give conjectures on Hankel determinants and higher order recursions.

Speaker : Pawel Hitczenko Keywords: Analysis of algorithms; Walsh-Hadamard transform; recursive algorithms; average case analysis; central limit theorem martingale. Abstract: We analyze the performance of a family of algorithms for computing the Walsh-Hadamard transform. One aspect of performance is modeled by a family of reoccurence relations. Deterministic bounds on the solutions are obtained, and under natural random model, we find, asymptotically the expected values, variances, and also...

Speaker : Persi Diaconis Keywords : Analysis of algorithms; poissonization; conditioned limit theory; Lecams method; Bayes theory; definettis theorem. Abstract : Poissonization can be abstracted to a wide ranging method for randomizing a perimeter to make components independent. This allows us to handle exponential structures, random matrices and much else. There are many ways of derandomizing. I will feature Bayes theorem and Lecams method.
